Physical Description
Ammonium thiosulfate is a white crystalline solid. It is very soluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. It is used in photography, in chemical analysis, and for many other uses.
Ammonium thiosulfate solution (60% or less) appears as an odorless colorless liquid. (USCG, 1999)
